In which waters of our country are there finless porpoises? What are the habits of the finless porpo

In our country, the finless porpoise.

The distribution range includes the Bohai Sea and the Yellow Sea.

Waters such as the East China Sea, the South China Sea and the Yangtze River. The finless porpoise is currently the only freshwater mammal in the Yangtze River.

At present, the number of finless porpoises is less than 1,000, and the number is still decreasing. They are in the Yangtze River food chain.

but relatively timid, most of the finless porpoises do not approach the boat. They prefer to move alone and feed on fish, shrimp, etc. It has a sound like a sheep's cry, has a lively personality, jumps up and down in the water, and swims with human boats, so it can be said to be a cute animal.

The finless porpoise has a grayish-black or grayish-white body, a short head, a slightly protruding forehead, and no dorsal fin, so they do not often jump out of the water. The ventral surface has two flippers, some of which have a reddish tinge and are particularly prominent during the breeding season. The finless porpoise is currently a first-class protected animal in China.

Known as the "giant panda in the water", it is now a functionally extinct species. The number of them counted in 2006 was more than 1,200 and will decrease on average every year, making it urgent to protect them.

The finless porpoise has been recorded in ancient times, Han Yu.

He once wrote in the poem, "When the finless porpoise is playing, the waves are flickering." But the current situation is not encouraging. There are many reasons for their sharp decline, chief among which is human activity.

Human hunting, environmental pollution and food shortages have all contributed to the decline of the finless porpoise population. The establishment of protected areas and the implementation of a ban on supplementation can bring a ray of life to the finless porpoise, but it is far from enough, and we should do to protect the ecological environment and make scientific plans for their reproduction.

In China, in fact, not only the finless porpoise, but also many animals are facing survival problems. They live in this world, they all have different beauty, how to coexist with them harmoniously should be a problem we strive to study, after all, no one wants our children and grandchildren to be only in books or natural history museums.

to see them.

The finless porpoise mainly lives in the Yangtze River in China, and is the only mammal in the Yangtze River, they rarely jump out of the water, the requirements for water temperature are more extensive, they rarely show the water, like to churn in the river and so on.

There are finless porpoises in the waters of the Bohai Sea, the Yellow Sea, the South China Sea and the Yangtze River in China.

There are finless porpoises in the waters of the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and the Yangtze River in China, the finless porpoise likes to live at the junction of freshwater and saltwater, and can also live in the downstream freshwater areas of large rivers.

Dolphin. The finless porpoise first lives in a completely different environment, one lives in seawater and the other lives on the boundary between saltwater and freshwater in the offshore water, belonging to different classifications, and the finless porpoise does not have a dorsal fin. The evolutionary history of the dolphin family dates back 10 million years and there are 40 species, killer whales.

Belongs to the large dolphin family.

<> finless porpoise belongs to two different families. The most significant difference in appearance is the absence of a dorsal fin, which is why the finless porpoise is called the finless porpoise in English. Another nickname, the "Right Porpoise", describes the same trait.

Dolphins, often a very broad term, encompass quite a few species, even in axons.

There is also considerable variation in the lower (genus and below). The biggest difference between dolphins and dolphins is the taxonomic location, dolphins belong to dolphins and dolphins belong to two different families. The most obvious difference in appearance is that dolphins do not have dorsal fins, so it is also known as finless dolphins.

Dolphins have smooth body hair and a pliable and pliable body.

Well, very good at jumping and swimming, and also the fastest mammal in the water.

Possess a very intelligent brain and a well-developed sonar.

They rely on the sound waves of sonar for echolocation during activities, and they have a good ability to listen in water and air, and the nostrils of dolphins grow on their heads, which is convenient for drinking water and breathing, the smallest dolphin is about 1 meter long, about 30 kilograms, and the largest dolphin is about 10 meters long and 14 tons, each dolphin presents different morphological characteristics, the brain is very developed, and it has an extraordinary memory, and humans train dolphins to make a lot of difficult movements, with a high IQ and a friendly personality, many people like dolphins.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The living environment is different, the area where the dolphin lives is in the seawater, but the area where the finless porpoise lives is at the junction of saltwater and freshwater, and the finless porpoise has no fins on its back, so the volume is different. The size of the dolphin is much larger than that of the finless porpoise.

Different classifications, different body types, different appearances, different diets, and different living environments. Finless porpoises do not have dorsal fins.

Finless porpoises and dolphins are two different animals. Dolphins are larger in size, while finless porpoises are puffer fish and are smaller in size. Dolphins are not poisonous.

It is a species of mammal
